Feature:1. Salinity meter, can be specially used to determine the salt concentration in liquid or food.2. Adopt ABS shell, copper testing top, corrosion resistance and long service life.3. LED display panel, red light indicates salt concentration, green light indicates power.4. Place the probe above the liquid surface for at least 2 seconds, then the result will appear.5. Sensitive response, high measurement accuracy, compact and portable, easy to operate.Specification:Condition: 100% Brand NewItem Type: Food Salinity TesterMaterial: ABS, CopperModel: THE01402Battery Adaptation: 4 x LR44(AG13) Button Battery (Battery Not Included)Test Standard: The temperature of the tested object is 60-80℃, and test is 2-10 seconds (commonly used salty standard, theory: 993 grams of water and 7 grams of salt give a value of 0.8-1.0)Power Input: 4x1.5=6VWorking Current: Maximum 20mA (LED All On)Measuring Range: 0.3%-2.0%Applicable Temperature Range: 60℃-80℃Calculation Formulas: Salt Content = Total Mass x Concentration (For Example: If the total mass of 1 cup of solution is 150g, the concentration is 0.5% 150g x 0.5%= 0.75g)Size: Approx. 212x24.8x15.4mm / 8.3x1.0x0.6inFunction Description:1. Probe: test salt concentration2. The 7 red LEDs respectively indicate the salt concentration:0.3% (moderate standard)0.6% (1.5 times salty)0.8% (2 times salty)1.0% (2.5 times salty)1.3% (3 times salty)1.7% (4 times salty)2.0% (5 times salty)3. 1pcs green LED for power indicator4. ON button: Press the button and hold it down, the test can be performed when the power is turned on, and the test will stop when it is released.Instructions for Use:1. Check whether the salt tester probe is clean. I
